If specific columns have value then put Yes

This might be a basic question but I am wondering if there is a formula or macro that can help me out.

This is what I am looking for:

If certain specific cells contain values, then another cell will put a "yes" in it.

Ie.) If Cells A1, B1, C1, D1 have a value in it then cell E1 should say "yes". If one of these cells is blank then E1 should either be blank or say "no".

Currently the formula I have is:

=IF(ISBLANK(A1), IF(ISBLANK(B1), IF(ISBLANK(C1),IF(ISBLANK(D1), "",D1,C1),B1),A1)
(This doesn't work as the error "You’ve entered too many arguments for this function"

=IF(ISBLANK(A1), IF(ISBLANK(B1), IF(ISBLANK(C1), "",C1),B1),A1)
(This formula does work though as it has less arguments)


Please let me know if this is possible. Thank you in advance for your help
